Gerard Butler licks the cheek of costar Katherine Heigl at the premiere of their new romantic comedy, The Ugly Truth, held at Pacific’s Cinerama Dome on Thursday (July 16) in Hollywood.

Gerry, 39, made an appearance on Thursday’s episode of The Tonight Show with Conan O’Brien. When asked about his Bounty Hunter costar Jennifer Aniston, he admitted, “We’re very much in love. Especially her. We’re actually going to tie the knot next Tuesday.”

Gerry then let everyone in on the joke, saying, “And then on Saturday, I’m marrying Cameron Diaz. Joan Rivers will be the next weekend.”
